To all whom t may concern Be it known that JOHN H. STEWART and JOHN M. SoHnNx, citizens of the United States of America, and residents of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements inV Loading Mechanism, of which the following is a specification.

Our invention relates to improvements in loading mechanism, and the object of our improvement is to furnish for that type of rotatable drum concrete mixers which are mounted for transportation suitable and convenient means for loading batches of unmixed material into the delivery opening of the drum. This object we have accomplished by the respective means and mechanisms which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is an end elevation of our combined loading and dumping means for a concrete mixer, showing the mixer drum in its dumping position, while they loading f b'ucket is at the same time in its lowered position ready to be filled. Fig. 2 is an end elevation of said device, showing, however, the mixing drum in its position ready to be filled by the elevated dumping bucket.

Similar numerals of reference denote corresponding parts throughout the several views.

Themixing drum 55 is of the rotatable, tiltable type, closed at one end, and having a large orifice in its opposite, end commonly used for both receiving and delivery purposes. Said mixing drum is mounted rotatably within the frame 47 of the machine, being hung on trunnions in the usual way with a pinion, not shown, in mesh with the exterior gear ring on said drum, said pinion being driven by intermediate gearing, not shown, actuated by means of the rotary driving shaft of the machine. The trunnions 48 of said drum are mounted to rock in bearings, not shown, supported on the arched plates 43 of the machine frame. The machine frame 47 is mounted on a truck 73 having carrying wheels 74. The frame 47 is a hollow skeleton box-form construction, whose uprights and cross beams are supported by oblique braces. The drum 55 is so mounted in said frame as to rock transversely thereof, and is supported at a suficient height so as to conveniently dump its contents when mixed into a receptacle at one side of said frame, such as a barrow 75. Gn the opposite side of said frame 47 from said barrow is located the loading device of the machine. rlhis comprises an opentopped bucket 67 the side thereof nearest said frame being peaked or drawn out toward the machine like the similar delivery lip of a coal scuttle. The numeral 69 denotes a pair of arms located on opposite sides of said bucket 67 and pivotally connected thereto at their cuter ends at 68, while their inner ends are pivotally connected at 66 to the frame 47 of the machine. rThe numerals -61 denote the telescoping parts of each of a pair of adjustable braces located on opposite sides of said bucket 67 and adapted to support the upper end of the machine frame 47 by means of the pivotal connections 59 of the upper ends of their'parts 60 with lugs on the said frame on its side adjacent to the bucket. The part 61 which is hollow and slidable over the part or rod 60 in each case, has its upper end provided with a set screw 62 whereby it may be secured in a desired position upon said lugs 60. lA collar 63 is slidably mounted upon the hollow part 61, and is adjustably secured thereon by means of a set screw 64. Each collar 63 is provided with an orificed lug 78 adapted to receive a downwardly hooked end of a swinging brace 65, whose other end is pivoted at 66 to the lower end of said machine frame. The said adjustable supports 60-61, when fully extended and supported in their outwardly spread positions by means of the arms 65, are adapted to contact with the ground or surface upon which the truck 7 3 stands, to afford a support to the said machine frame at the top thereof to counteract the leverage of the relatively heavily filled bucket 67 when the latter is being elevated to its dumping position. The swinging arm V65 may then be detached from the lug 78 following means are used: The numeral 70 denotes a bail mounted pivotally across the open upper end of said bucket and provided medially with a forked extension, between whose forks is mounted a sheave 7l adapted to carry the loop of the cable l0, one end of which is secured to the upper end of the machine frame nearest said bucket. The cable l0 is after being carried about the sheave 71, brought upward and carried about a rotatable sheave 72 mounted at the upper end of the machine frame 47, and

thence carried about another sheave, not

shown, and directed downwardly to have its other end secured to and wound about a winding drum not shown Xedly mounted upon the driving shaft of the machine.

The dotted lines in F ig. l indicate the horizontal position of the filled bucket 67 just before its lip comes in Contact with the cross-bar 58 of the bracket-arms 56. In Fig. 2 the bucket 67 is shown elevated still further, its lip having engaged the bar 58, which tips the bucket over so that it delivers its contents into the drum 55, when the latter has been tilted into the position shown in F ig. 2 by means of the mechanism to be hereinafter described.

lt will be observed, that the arms 69 are fulcrumed at the lower part of the frame 47, which permits the elevating means t0 exert upon them and their load a direct pull and constant turning movement from the beginning of actuation, and preventing any strain due to the overcoming of a dead center, such as might be necessary if the arms were ulcrumed above the points shown.

Having described our invention, what we claim as new, and desire to secure by Letters Patent is:

ln combination, a skeleton frame consisting of pairs of side standards connected to gether rigidly, a pair of like arms hinged for up and down swinging movements to one side of the bottom of said frame, a vessel having a delivery-lip directed toward said frame, said vessel being pivotally mounted in equilibrium between the outer ends of said arms, and provided with a pivoted bail, means operatively connected to said bail adapted to swing said vessel and said arms up and down, and a stop-bar bracketed on the frame above the mouth of the receptacle and in the path of movement of the lip of saidvessel to tilt the latter and deliver its contents when the vessel is moved toward its uppermost position.

Signed at Waterloo, Iowa, this 18th day of June, 1914.
